Add global chats to warmane API

Hi there,

I suggest adding the global chats of realms to the warmane API (read-only). Since almost all LFM is happening in these chats, I see myself afk-ing a lot and scrolling global chat while logged in, only to check if an interesting raid is going on (I think I am not the only one doing that). Making global chats available via the API, would make it for example possible, to mirror them in Discord or other chat applications. This way people can log in as soon as an interesting raid is going on and not be afk ingame that much. This would also reduce load on the server.

Thanks!
